yeah wish i could help more , but you have to enter an almost URL looking thing where it says computer .. i forget what it was . im sorry
EDIT: i remember using a third party app which you installed a server client on the PC and then a program on the WM device , i cant for the life of me find the program on my backup hard drive or online . i dont remember what it was called . but it set up and did everything perfectly . it even had options for streaming video as well . like i have a TV tuner on my dekstop and i was able to stream it to my TP2 and watch TV from there i loved it and i hate myself for loosing it
